Hexosyltransferases
BRITE hierarchy
Sysname
UDP-glucose:alpha-D-(1->3)-glucan 3-alpha-D-glucosyltransferase
Reaction(IUBMB)
UDP-glucose + [alpha-D-glucosyl-(1->3)]n = UDP + [alpha-D-glucosyl-(1->3)]n+1 [RN:R03996 R06045]
Reaction(KEGG)
Substrate
UDP-glucose [CPD:C00029];
[alpha-D-glucosyl-(1,3)]n [CPD:C02616]
Product
UDP [CPD:C00015];
[alpha-D-glucosyl-(1,3)]n+1 [CPD:C02616]
Comment
A glucan primer is needed to begin the reaction, which brings about elongation of the glucan chains.
